Superplasticisers

Oscrete Performance Additives has a comprehensive range of powder superplasticiser to cover a variety of applications.

Superplasticisers can be used in three ways: to create flowing, self-leveling concrete without increasing water, without reducing cement and without sacrificing strength; to produce workable, high-strength concrete by reducing the water and thus the water-cement ratio; or, to save cement by reducing both the water and cement contents while maintaining the same water-cement ratio and the same workability.

The main benefits of superplasticisers can be summarised as follows:

Increased fluidity:

• Flowing
• Self-leveling
• Self-compacting concrete
• Penetration and compaction around dense reinforcement

Reduced W/C Ratio:

• High early strength
• Higher ultimate strengths
• Reduced shrinkage, especially if combined with reduced cement content
• Improved durability.
